Operation
PACKING LIST
- RUISHAN Precision Balance
- Weighing Pan
- Weigh Pan Holder(It is already fixed on the scale by default.)
- Power Cord
- User Manual
- 500g CAL. WEIGHT (0.1g accuracy products do not include CAL.WEIGHT.)
Note : This product does not contain batteries and data cable.
INSTALLATION
- CHECK FOR DAMAGE-Open the package and ensure no parts were damaged during delivery. Make sure all parts shown in the packing list are included.
- Place scale on a flat, stable working platform.
- Assemble the balance by snapping the weighing tray into the base.
- Attach power cord and plug in device. The scale accepts 110V. Please confirm the correct voltage before using the scale.
- Do not overload the full capacity of the balance. If there is an error, calibrate the scale.
GETTING STARTED
- Place on a stable surface. Screws on bottom of balance can be adjusted to stabilize instrument.
- Press the Power button to turn instrument on. Allow the unit to warm-up for 15 minutes.
- When the balance is turned on, it will show the max weighing range and accuracy. For example:
- “1000.01” means a capacity of 1000g and an accuracy of 0.01g.
- The balance will display numbers 1 through 9. Once it displays “O” the balance will be ready to calibrate.
CALIBRATION
- Turn on the scale.
- Press Tare/Cal button until the display shows CAL.
- The display will show a weight (eg.1000g). Place the corresponding standard mass on the weighing pan. (The balance has the function of automatically identifying the weight of the weight and calibrating it. It is forbidden to put weights that exceed the rated capacity)
- Remove the standard mass once the display is stable and accurate.
NOTE : If this is the first time using the balance, repeat the calibration steps 2-3 times. Please make sure that the scale is placed stably during calibration or use.
Linear calibration
- Long press Tare/Cal, it will display “CAL”, release the button, the display will show a weight. Long press again the button of Pcs/Unit, the scale will again display CAL, release the button, the scale will display a weight (eg:2000.00), put a 2kg mass on the plat, a few seconds later it will stable display the number of “2000.00g”. Remove the mass on the scale, it will display a weight again(eg:1000.00), put a 1kg standard mass on the pan, follow thesame step untill the scale automatically return to zero after the weight is removed.
- Suitable for RST series products of 0.1g and 0.01g.
Note : When the product can work normally, please do not operate this step.
TARE (CONTINUED)
- When the weight of the item to be weighed is not more than 2% of the total range, short press TARE/CAL (T <2s), and the balance will return to zero. The zero setting indicator on the display will light up. The balance can still weigh at full scale.
- When the weight of the item being weighed is greater than 2% of the total range, short press TARE/CAL (T<2s), and the balance will return to zero, The tare setting indicator on the display will light up. The balance cannot be weighed in full capacity . At this time you should check the remaining weighing range on the loading progress bar. Only weigh in the remaining range
COUNTING FUNCTION
Used to count number of parts by extrapolating from original sample.
- Press Pcs/Unit. The balance will display 10, 20, 50, 100 in cycles.
- Select from 10, 20, 50, 100.
- Place the corresponding number of units on the scale. For example, if you chose 10, then place 10 units on the scale.
- Press PCS key to confirm.
- Add or remove pieces from the pan and the scale will display the number of pieces used. For example, add 3 and the scale will display 13.
- Press Pcs/Unit again to exit counting function.
